Writing "0xE4" to OFDCR2 with OFDCR1="0xF9" enables the oscillation frequency detection, and
Setting "0xF9" to OFDCR1 enables writing to OFDCR2 and setting "0x06" to OFDCR1 disables writing
After writing data to OFDCR2, set "0x06" to OFDCR1 to protect OFDCR2 register.
The oscillation frequency detection is available only in NORMAL and IDLE mode. Table 19-1 shows the
